There's a specific reason that Sidewalk is an independent company with a very different mandate and behaves in a very different way. That's because it operates independently from Google, both on data protection as well as the way it's working through the product development in Toronto.
I don't have an opinion on how Sidewalk is conducting their business. The parallels that exist only exist because there is a broader global conversation around data protection and privacy, as well as development of both urban and rural areas.
